Hi List,
I need to update large table sub_svc_parm ( over billion rows). This
is PL/SQL block that does it:
I want to rewrite so it is executed as single SQL update statement.
Any suggestions ?
DECLARE
v_sub_svc_id sub_svc_parm.sub_svc_id%type;
v_val sub_svc_parm.val%type;
CURSOR cur_dgid_update IS
SELECT /*+ FIRST_ROWS */ b.sub_svc_id, d.destination_group_id
FROM sub_svc a, sub_svc b, sub_svc_parm c, RATE_CENTRE_TEMP_&1 d
WHERE a.SUB_ID = b.SUB_ID
AND a.SVC_ID = 10000
AND b.SVC_ID = 10008
AND a.SUB_SVC_ID = c.SUB_SVC_ID
AND c.parm_id = 10230
AND SUBSTR(c.val,1,6) = d.npanxx;
BEGIN /* Main */
OPEN cur_dgid_update;
LOOP
FETCH cur_dgid_update INTO v_sub_svc_id, v_val;
EXIT WHEN cur_dgid_update%NOTFOUND;
UPDATE sub_svc_parm
SET VAL = v_val
WHERE sub_svc_id = v_sub_svc_id
AND parm_id = 12650;
END LOOP;
CLOSE cur_dgid_update;
-- COMMIT;
END;
